Question

Jenna and Becca were both selling cookies door to door. Jenna sold 8 boxes of cookies for every 3 boxes of cookies Becca sold. Combined, they sold a total of 385 boxes of cookies. How many boxes did each girl sell

Answer 1

Answer: Jenna sold 280 and Becca sold 105 boxes.

Explanation:

Let 3x be the number of cookies Becca sold.

Then, the number of cookies Jenna sold = 8x

Since Combined, they sold a total of 385 boxes of cookies.

So,
`3x+8x=385`

`\Rightarrow\ 11x=385\\\\\Rightarrow\ x=(385)/(11)\\\\\Rightarrow\ x=35`

So, Jenna sold 8(35) = 280 boxes

and Becca sold 3(35)= 105 boxes

Hence, Jenna sold 280 and Becca sold 105 boxes.
